INTRODUCTION

This application note details the tools, supporting

technologies and procedures for the development of

infrared applications on Windows XP® based PC.

A Windows XP (WinXP) application that interfaces with

an embedded system via IrCOMM is included in the

appendices of this application note. This source code

demonstrates the use of the Windows®Application

Programming Interface (API) required for IrDA®

standard IR communication on Windows XP based

platforms.

Appendix A: “Example Irda® Standard System

Description”describes the system and documents the

tool used to create this Windows XP application

program, while Appendix B: “Win XP Source Code -

IrDA DEMO.CPP”through Appendix C: “WinXP

Source Code - IrDA DemoDlg.cpp”is the WinXP

Application Program source code.

FIGURE 1shows an IrDA standard system, where a

Windows XP based PC is communicating with an

embedded system. In this system, the PC operates as

the Primary device (Client) and the embedded system

operates as the Secondary device (Server). The terms

Client and Server are used in reference to Windows

(PC) programming, while Primary device and

Secondary device are terms used by the IrDA

standard.
